PUMPING BEAM.

Application filed March as, 1925. Serial 1&0. 19,077.

This invention relates to an apparatus for pumping deep oil wells, and more particularly to a novel construction of means for supporting and counterbalancing the pumping beam, to eliminate the trouble and ditficulty usually experienced by the break ing of the rod lines from the power to the well.

In carrying out the invention I contemplate the provision of a novel counterbalanced pumping beam adapted to be. operated directly from the pull rod, which conveys motion from a. power plant or the like directly to the counterbalanced beam.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawmg, the invention residing in the construction, "combinationand arrangement of parts as claimed.

Figure 1 is a side elevation."

Fi ure 2 is a view taken at a right angle to Figure 1.

Figure 3 is a perspective view of the counterbalancing support.

Figure t is a sectional view on hne 4-4 of Figure 1.

Figure 5 is of Figure 1.

Figure 6 is a sectional View on line 6-6 of Figure 1.

Figure 7 is a sectional view through the counterbalance.

Referring to the drawings in detail, 10 represents the base and structure upon which is supported the Samson post 11. These posts are braced and supported by guy rode a sectional view on line 5--5 12, each of which is equipped with a turn.

,buckle 13, there being preferably four of such rods employed as alearly shown. The

pumping beam is pivoted on these posts, and is preferably made up of two channel irons indicated at 1 1, although it may consist of an I beam or a beam of any other cross sectional contour. Secured to the base 10 for each post 11 is a plate 15 of any suitable construction from which rises a post 16 received by the lower end of the adjacent post, while the upper ends of these posts receive similar osts 17 which depend from a block 18 designed to connect the adjacent ends of said,post and also constitute a pivot support for the pumping beam. This structure is clearly shown in Figure 5, wherein it will be noted that the upper ends of the posts are also connected by a transverse rod 19' which passes through the-block 18, the latter being recessed to accommodate the beam support proper indicated at 20 which is mounted upon a pivot rod 21 passed therethrough and also through the separate portions 22 of the block defined by said recess. The support 20 includes a web 23 which is arranged between the channel irons 14 of the beam as shown in Figure 5. In addition to mounting the pumping beam in the manner just described, it will be noted upon inspection of Figure 2 that the Samson posts converge toward their upper ends, affording said posts side bracing strength, one with relation to the other as well as providing for a strong main pivot bearing. One end of this beam is provided with any suitable means for association with the well rod 24 as this does not form any part of the present invention, while suspended from the other end of the beam is a counterbalance 25. While this may be of any suitable construction, it preferably consists of a block of stone, concrete or the like, in which is embedded the spaced tubular members 26, the latter projecting beyond one end of the counterbalance to support it in spaced relation to the ground. Rising from this counterbalance is a rod 27 one end of which is embedded as shown and the other end passed through a tubular member 28 received by depressions 29 in a block 30 which is formed with a web 31 adapted to pass down- Wardly between the channel bars, and secured thereto by means of a suitable fastening element or bolt 32. The beam is of course operated by a vertical pull rod 33 which depends from the beam at a point hehind the pivot therefor, the rod 33 being connected with a horizontally disposed reciprocating rod 34. This vertical pull rod 33 is preferably made up of two members shown in Figure 4, and which members are secured to the adjacent portion 35 of the block which includes a portion 36 arranged between and bolted to the channel members 1 1 of the beam, the block also including flanges 37 upon which the flanges of the beam repose, it is manifest, from the construction shown and described, that I have devised an improved means for supporting a counterbalanced umping beam for deep oil wells, counterba ancing the gravity load IOU of the rods from the power to the well in .a manner to eliminate breaking of said rod with a consequent loss of time, labor and oin descri tion the nature and advanta es g a P a b of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fallrwithin the scope of what is claimed.

Having thus described the invention, I claim:

1. In a device of the character described, a base, hollow posts rising therefrom in convergent relation, a bearing block including' portions fitted in theupper'ends of the said posts, and having its upper surface recessed, a pumping beam, a support therefor fitted within the recess of said bearing andpivotally associated with the latter, guy rods bracing said posts, a counterbalance suspended from one end of said beam, and means for operating said beam.

2. A pump device comprising a pair of upwardly converging hollow posts, a hearing block bridging the space between the upper ends of the posts and connected therewith and having its upper surface recessed, a beam, a support therefor extending into the recess and pivotally connected with the bearing block, a pair of guy rods for each post, said rods being connected at opposite sides of the top part of the post, a counterbalance connected with one end of the beam, means for connecting the other end of the beam to a pump rod and means for operating the beam.

In testimony whereof I affix my signature.
